A few hundred years into the future, Celestia's age is finally showing; however, the mare refuses to give up her title as the Princess of the Sun. In her attempts to stop her, Luna uncovers some rather dark secrets her sister has been hiding...

As stubborn as the mare is, Celestia continues to lower and raise the sun. Getting angry, Luna declares it's enough and forbids the rise of the sun until another Sun God is appointed, accidentally causing Equestria to split in two and a massive war to break out.

A play off of The Solar Empire and The New Lunar Republic, along with The Changeling Swarm (and a few extra dark elements added)

This story jumps from the viewpoints of many characters, showing each side of every event: i.e, Luna's side and Celestia's side of the war. If it grows confusing, I'm sorry ;-;

Crossover is listed because a few other grim darks/creepypastas are briefly mentioned at some point or another.
